ATTACHMENT FOR MOTOR VEHICLES.

Application filed November To all whom it may concern: w

Be it known that I, ABRAHAM l/Vnrss, a citizen of the United States, residing at New York, in the county of New York and State of New York,.have invented certain new and useful Improvements in Attachments for Motor Vehicles, of which the following is a specification.

This application is a continuation in part 0 of the one filed January 23, 1923, Serial No.

614,363. The invention relates to motor veliicles, particularly taxiineter vehicles. Frequently when the vehicle stops in heavy traflic, while unoccupied, a prospective passenger runs up to the vehicle and in an attempt to enter the same either to steal a ride or because of being in a hurry, opens the door without first notifying the driver. It, at the moment when the door is open, the vehicle is set in motion, an accident may result to the prospective passenger. Accidents to the passenger or damage to the car I also often result, when the door opens, While the vehicle is in motion.

such accidents or damages, which I accomplish, according to the present invention, by electrical means so arranged between the door of the vehicle, the motor and the flag or handle of the taximeter, that when the door is opened, while the flag is up, when the vehicle is not occupied, the motor will fail to start, or will stop when thedoor opens, while the vehicle is in motion.

My invention has also other objects in view, which will appear from the detailed description thereof.

In the accompanying drawing in which similar reference characters denote corresponding parts, Fig. 1 'is a side View of a vehicle partly in section showing my new device; and Fig. 2 is an enlarged cross section of a part of the vehicle and taXimeter showing details of the electric means.

10 denotes a taximeter vehicle of usual construction, employing, for instance, a high tension magneto 11 to produce ignition. 12 denotes the usual fiag controllcd fare register or clock-and 13 denotes a door leading into the passenger compartment. 16 denotes a switch adapted to be controlled from the flag or handle 12. The contact members 1G, 16 of the"fiag switch 16 are so arranged that normally, that is, when the flag is up or in a position indicating vacant, the contact members 16', 16 are The object of the invention is to prevent 9, 1923.

closed, as shown in Fig. 2. 17 denotes the wall of the vehicle to,which the door is hinged, as at 18. Between the opposite edges otf'the door 13 and of said wall 17, I

provide a switch, which, according to the lows In a groove 19 provided in the wall and open at its outer end, is mounted a cylindrical casing 20 of insulating material, the outer open end of which is closed by an annular member 21 of conductive material. Slidably mounted in the cylinder 20, is a disc 22 of conductive material, which is actuated by a spring 23 one end of which is fixed to the inner face of said disc 22 and the other end to a pin 2% of conductive material projecting through a perforation in the inner end wallo'f the cylinder. The outer face of said disc 22 has screwed or otherwise fixed to it, a plug or pin 25of non-conductive material, which projects through and is guided in the annular member 21.

The spring 23 tends, when the door is open, to force the pin 25 outwardly and hold the disc 22 in contact with the inner face of the member 21. When the door is closed, its edge 13 will depress the plug 25and as a result thereof, move the disc 22 out of contact with the member 21. The pin 24 forms one of the terminals of the switch and is connected to the ground by wire 26. The. member 21 is connected by a wire 27 to one of the contact members, as

16, of the flag switch 16, and the second contact member 16 of said switch is connected by wire .28 to the magneto 11.

It will be clear that when the door 01': the vehicle is opened, while the latter is unoccupied, as indicated by the switch in vacant position, the door switch will close, the disc 22 being forced outwardly intocontact with member 21. As aresult, the ignition circuit will become grounded and the motor fail to start., Thereby the drivers attention will be drawn to the door and only on lowering the flag or closing the door, could he again open the-circuit.

In case of a vehicle not using a taxiineter,

the switch in the door may be directly-comnected to the motor or its ignition system. In that case, whenever the door is opened, the ignition system will be grounded,.so that the vehicle will fail to move.

It is understood that the same results hereinbefore stated may beobtained by other means tran those described and instead of the ignition system, the gas or feed may be brought under the influence of a suitable means controlled by the manipulation of the door. I, therefore, do not'wish to restrict myself to the details described and shown. 1

What I claim is e 1. In a motor vehicle having a -register with a manual control, the combination with a door, of means controlled through said door and intervening between the motor and said manual control of the register, whereby 1 the motor will be rendered ineffective, when the door is open,-while the manual control is in inoperatlve position.

2. In a motor vehicle having a flag controlled fare register, a door and an electricallyrcontrolled gas ignition system, of a switch controlled through said door, a

In testimony whereof I aifix my signature in presence of two witnesses.
